APPLICATION NOTES

APPLICATION CIRCUIT

• Bel's surface mount 10Base-T network component filter modules provide the complete solution as the interface

module between the IC transceiver chip and the media side connector. Designed within each module are transmit and

receive filter networks, high voltage isolation transformers and high performance EMI suppression common mode

chokes. Each module fully meets the IEEE 802.3 standards to 10 Mbps data rates over 100 meters of media cable.

• All of these part types have been designed to provide signal performance optimization, maximum noise reduction and

minimum crosstalk interference. Careful board layout and grounding techniques are also critical to control jitter and

signal reflections.

• Bel's low profile, surface mount packaging is ideal for high speed pick and place machinery. Parts can be shipped on

tape and reel for high speed placement. Construction processes have been implemented for thermal compatibility

with high temperature IR reflow assembly processing. Post dipping of leads assist with PC board solderability. Each

part is optically inspected to meet rigid coplanarity requirements.
